Choose small, low consequence slopes.

Slabs formed overnight will likely remain reactive to rider traffic.

Solar input could increase sensitivity to triggering.

Avalanche Summary

There are no recent avalanche reports for this region.

If you are going out in the backcountry, please consider sharing your observations to the Mountain Information Network (MIN).

Snowpack Summary

By the morning of the 18th up to 30 cm of new snow may have fallen. This will be accompanied by strong southerly winds forming deeper deposits on north aspects.

15 to 40 cm overlies a crust on south aspects and all aspects below 1800 m. A layer of surface hoar could be found just above this layer in sheltered terrain at treeline.

Snow depths at treeline are around 80-90 cm.

Weather Summary

Tuesday Night

Cloudy with 10 to 30 cm of snow expected. 60 to 80 km/h south ridgetop wind. Treeline temperature -3 °C.

Wednesday

Mix of sun and cloud with up to 5 cm of snow expected early in the morning. 30 to 50 km/h southwest ridgetop wind. Treeline temperature -2 °C.

Thursday

A mix of sun and cloud with trace amounts of snow expected. 40 to 60 km/h south ridgetop wind. Freezing level rising to 2100 m, with the potential for a temperature inversion and colder temperatures at valley bottom.

Friday

Mostly sunny. 30 to 50 km/h southeast ridgetop wind. Freezing level rising to 2300 m.

Terrain and Travel Advice

  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Be careful as you transition into wind-affected terrain.
  • Be alert to conditions that change with elevation and sun exposure.

Avalanche Problems

Storm Slabs

Reactive storm slabs will likely have formed overnight. The largest and most reactive slabs will likely be found on northerly aspects.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible - Likely
